When you are writing a formal letter to a company, what information do you include:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Both your address and the Company's address
A formal letter carries the sender's address at the top, so that the company can reply, and the receiver's address (the company's name and address) before the salutation, so that the letter reaches the right office and is on record.
Why the Other Options are Incorrect?
Option 1: Your address — Incorrect. It is needed, but only half of what a formal letter carries; the company's address is left out.
Option 2: Your date of birth — Incorrect. Personal details such as the date of birth are not part of the letter format.
Option 4: None of these — Incorrect. Option 3 gives the right answer, so "None of these" cannot be correct.
